Considering the power boost the base races got in PF, it's not hard to make Genasi balanced against them with no level adjustment or anything. Here's my attempt at such...
Earth Genasi
+2 Str, +2 Con, -2 Cha
Medium-sized Humanoid
30 ft. base speed
+1 Natural Armor bonus
Stonecunning
+1 racial bonus on saving throws against earth spells and effects, and an additional +1 for every 5 for every five levels
+2 racial on Appraise and Craft checks relating to stone or metal
Darkvision 60 ft
Automatic Languages: Planar Trade, home region
Bonus Languages: Any (except secret)
It seems overpowered right now. At least, I don't feel like there's a good reason to play a Dwarf anymore, the Earth Genasi just reads as a better Dwarf in a lot of ways. I figure dropping either natural armor or acid resistance would solve it, which would be a better idea to get rid of?
Thanks for any critiquing.
EDIT: Acid resistance dropped.
Probably the acid resistance would be better to lose. I've never really agreed with the earth=acid assignment in 3e. Which makes more sense for a man made of stone: tougher skin or resistance to corroding?
