I was unhappy with my first attempt at this. Even though I took over the continent, my elepult war was so late that I found myself hopelessly behind the rest of the world.
This time, I settled 1E (this had minimal impact, really). Tech path was mining> BW> wheel> pottery> myst> AH> writing> masonry. I settled on the stone first, and the marble with my 2nd city. This pretty well crashed my research. I also
had to settle the sheep/phants sooner than I wanted to keep Peri out. So I built cottages wherever I could - luckily there's no shortage of riverside grassland - and struggled to writing. Libraries went up everywhere and scientist were run. I chopped out the mids in Cahokia, which really gave

a boost. No religion was founded on our continent, so I reserached CoL> Med after bulbing alpha and trading around. With all of the scientists I was running I was able to found an academy in Cahokia, bulb alpha, and bulb Philosophy, founding Taoism in the stone city. I build AW in Cahokia and ran priests to get a prophet for the shrine (which enabled me to take back the pisgs from Pericles). I headed to lit, but was beaten to the GLib by 2 turns - I chopped all my trees for the mids (it was late) so I had none left. After that it was a straight shot to lib, with some trading with my friendly neighbors.
Here's a shot of my cities at 1230AD (I'll take the barb city at the top next turn). My most advanced units are swordsmen (I think I have 2) and catapults (I have 1).
I took nationalism from lib, then went music> MilTrad> GP. I built cuirassiers everywhere while heading for rifling. Just as I was getting ready to attack Pacal he asked to peace vassal. Since he had lots of good techs and strong research, I agreed and attacked Pericles instead. After taking all of his mainland cities I capped him, leaving him with several cities on the SW islands. I met the rest of the world soon - I was ahead militarily at first, but Joao, Cath, and Gandhi were all teching very well. KK was isolated, which left him way behind and made him my logical next target:
He capped after I took 3 cities. Meanwhile, I headed for AL/ combustion/ flight/ industrialism while my vassals researched things like MilSci, Physics, Bio, Electricity, and Radio. When I had a large oil navy and a mixed invasion force of fighters, bombers, marines, paras, and tanks, I declared on Joao. He was the logical first target, being the most advanced and with only 2 sources of oil - one of them on my continent, which I took on the first turn of the war. Catherine had no oil, and Gandhi was doing a terrible job going for culture, with only rifles defending. I decided to take Lisbon capital first, since it was loaded with wonders and was the engine of his empire. Marines did the trick after naval and air bombardment:
Joao capped after I took 3 cities (I razen the one on top of his only oil), but I gave him his 2 remaining cities back - they were swamped in culture. Russia was next - she was going for culture but had only a small army (no stack), so I took all of her cities by one that was embedded in Joao's culture. I took 2 cities on the first turn of the war, and rolled through her easily:
The turn that I declared on Gandhi a diplo vote came up, so I picked Diplo Victory and won on the next turn:
Gandhi was willing to cap anyway after I took 2 of his cities last turn:
