I'm working on an ancient scenario myself and might want to reuse some of TAM's resources (mostly graphics), so I guess I better make sure I'm on a good footing with you guys
For a full-game mod, TAM doesn't exactly seem to have too many buildings (though granted I haven't really played it so I don't know how it works out in practice). Only 20 or so as opposed to 40ish for the default game -- and that's counting all those Smithies seperately which arguably should only count as one. My scenario only covers 150ish turns and I have more buildings than you guys (though admittedly I am deliberately aiming at great diversity). So here are some suggestions that I either have in my scenario or considered but rejected. It's free advice, do with it (or ignore it) as you wish
(I'm afraid Wonders is the one area of my mod I haven't really looked into yet so I can't be of much help there yet)
Garden/Zoo
Parks and Ornamental (zoological) gardens and the like were as common in the old days (as early as 1500 BC) as they are today. The Mesopotamians, Egyptians Persians, Greeks and Romans all loved them. The Hanging Gardens are of course the most famous but by no means the only example. Suggested effect: primarily Happiness, maybe culture.
Beer Hall
Main source of entertainment for the Egyptians. They met friends here, feasted, drank, played games and music, told stories, etc. Suggested effect: Happiness, Culture.
Police Barracks
Police is not a modern concept, it is as old as crime itself. In some societies and regions the military acted as police force, but especially in large cities and 'civilized' areas it was often a seperate organisation, in many ways very similar to modern police forces. Suggested effect: reduced War Weariness, Anarchy or Unhappiness.
Public Well
Clean water was a rarity in the Ancient world, even near rivers or lakes, since these were used for washing, bathing and sometimes as sewer. Wells are the one source of natural clean, high-quality drinking watter. Suggested effect: Health.
Brewery
Because clean water was so rare, and other drinks like milk and wine were luxuries usually reserved for the rich, beer was in most ancient (and medieval) societies the staple drink, with large-scale brewing being often a government monopoly. Suggested Effect: Health.
House of Life
A bit Egypt-specific, but for what it's worth: Ancient Egypt was very advanced in the field of medicine, especially compared to its neighbours, Egyptian physicians were highly regarded and oft-requested by other empires. The institution behind these physicians was the House of Life (Per Ankh), a mixture between a hospital, library and temple where the secret knowledge of medicine, magic and religious ceremonies was stored, and cures, spells, ceremonies and dream-interpretations where administered to laymen. Suggested effect: Health, Science, maybe Culture and/or Religion.
Work Camp
You have a whole bunch of smithies in your mod, but nothing to boost production. Work Camps or Workers' Villages were often erected at the sites of large building projects. Suggested Effect: Production.
Carpentry Workshop
Not very original, but effective as production booster. High-quality wood was rare in much of the Fertile Crescent (most of it was in Lebanon), high-quality carpentry even rarer. Suggested effect: Production.
Gymnasium
Originally a school and training grounds for sports in ancient Greece (used for military training in Sparta), they later also developed into educational institutes, hospitals, and gathering places for philosophers and sophists. The most famous examples are the Academy, the Lyceum and the Cynosarges, all from Athens (one or more of these might be suitable as Wonders). Suggested Effect: Culture, Science, Happiness, possibly Experience (but you seem to have that covered).
Festival (Grounds)
Festivals and processions were a common activity to unwind, celebrate life and honour the gods all at the same time. Suggested Effect: primarily Culture, maybe Happiness.
Arena and/or Circus
Chiefly Roman forms of entertainment, one for fights and one for races. I'm sure you've all seen movies like Ben Hur and Gladiator, so these don't need much further explanation
Suggested effect: Happiness.
Forum/Agora
Centres of commerce, politics, justice and cultural activities for the Romans and Greeks respectively. Suggested effect: Maintenance, Gold, Culture.
Aquaduct
We often think of them as Roman, but they were already built by the Assyrians as early as the 7th century BC (if not earlier). Suggested effect: Health.
Stoa
Ancient Greek version of our modern malls. Covered, often two stories high centre of commerce in which many shops and offices where located (also used for art displays and religious events). Suggested effect: Gold/Trade.
Odeon
Musical theatre. Ancient Greek/Roman version of our modern concert buildings. Suggested effect: Culture.
