I love regular old soy yogurts from the health food store tons.  Page 128 of "Ani's Raw Food Kitchen" has a killer recipe for an almond based yogurt.  It's easy to make.   sometimes I add a date or touch of agave nectar to sweeten just a little.  I also add some fruit if I have it. 

You can also ferment your almond yogurt.  Put it into a glass jar and cover with a cheezecloth.  Place it in a warm place for 8-10 hours.  Let it sit until it tastes perfect for you.
