I haven't tried this, but in the list's archives is a recipe for a
buttermilk substitute. Go to:

  No-Milk Mailing List: http://www.NoMilk.com/list.html

Looking at it I don't find much useful info. After a long discussion on
souring regular milk it has:

- Use of a non-dairy substitute to replace buttermilk in a recipe:  In
testing of non-dairy substitutes, I have learned that some non-dairy
substitutes work using the above method and others don't.  Don't be afraid
to experiment with brands that are available in your area.
