Well, in an E6 world lacking the high level divinations, reliable census data is probably hard to come by. I could see the humanoid lands being a lot like Hyperboria to the Greeks; no one really knows how many of who are out there, they just know there's a lot of them and they're not very nice.
Equatorial regions could go to the reptillian, by and large. Lizardfolk, troglodytes, kobolds, ophidians, yuan-ti, and so on. I like the idea of lost temples buried in the jungle. Its a good spot for dinosaurs too. And tribes of super-intelligent apes and savage Amazons, but that probably goes without saying.
I also like Giants. Fire Giants are CR 15ish, which is knocking on the door of godhood. With numbers like that, you probably only need one. Instead of being a separate race, The Fire Giant could be a regular giant who gets imbued with primal elemental force. That gives you Fire, Earth, Air and Cold, and Storm is easy to make a Water Subtype since they already get water breathing and a swim speed. If you didn't want every god to be a Titan, you could use giants.
Speaking of worshipping elemental forces, Elemental Weirds from the MMII are CR 12ish, cast as 18th level Sorcerers and get a list of at will divinations. You put a Fire Weird in the Temple of Fire, and you got a pretty good goto Elemental God right there. Its big, its mysterious, it knows things, people can petition it for wisdom.
