Here's a couple of ideas for races:
1. A byblical jewish race, as in, a race which will be similar to the Israelites as described in the bible:
Their units will be pretty weak, after all bronze was the commonly used metal back then and wasn't really that good, only a handful of byblical nations had iron at that time, and even that doesnt compare to steel, and no armor was used back then...
They would probably have the said bronze and iron (iron wielding units being very expensive) but would compensate for that by having powerful magicians.
Their magicians should along the prophet-like model, religious leader capable of powerful elemental spells (and possibly astral as well).
2. Race #1's counterparts, byblical pagans.
They would have slightly better units (cheaper iron units etc.) but instead of powerful elemental religious leader they would have sorcery-practicing mages, focusing on blood and death mainly.

You could also add this radical idea for a race, but I doubt it:
A race of hyper-intelligent LAND creatures, they would be powerful in astral magic and would have some strange special abilities, like an ability that has a chance to take over an enemy unit when striking it, and commanders could hypnotize the population for quick militia and possibly a magical mutation ability, changing humans units into freakish monsters.
Also, their mind control should render the target mindless.
