my motto is , kill, kill, burn, kill, take, take kill
first of all, calm down! -lol-
Okay, the advice I am going to give you will be the advice you do NOT want to hear. But, if you take it you will be able to warmonger far better.
Firstly, the fact that you asked for build orders in each age tells me that you are new to the game. That being the case you should take things in 'small steps' and build up to what you want. You will be a far more effective warmonger if you first learn the basic fundamentals of the other aspects of the game. So try this out as as 'build order' for your next few games:
1. Play peacefully and learn the nuances of worker management, tech research, and trading (read the war academy articles!)
2. Try different Civs with different traits.
3. Learn to defend yourself from attack - BEFORE you attempt to make others defend themselves from YOUR attack.
4. Once you start your warmongering stage - do it incrementally - war/long peace(20 to 40 turns)/war/long peace. Next few games - war/peace 15 to 25 turns)war/peace. Then go all out for an 'Always at War' game.
5. Forget about Wonders, until you feel comfortable with all the other aspects of the game - then check them out.
Now what I just told you may sound as if it will take forever - but it won't - trust me, in only a handful of games you will be on your way to the "kill, kill, burn, kill, take, take kill" player you want to be.
