I found something else, which for some reason eluded me before.

http://warhammerfantasy.wikia.com/wiki/Cytharai

This shows all the elven gods and a symbol for each. I will leave this here for other people in search of this =D
This is specifically for druchii, the asur and asrai have other versions of the mandala.
Here is a more general wiki entry: http://warhammerfantasy.wikia.com/wiki/Elven_Pantheon
