Hoogle is a great tool for finding haskell functions:

http://www.haskell.org/hoogle/

You can punch in the type of a function you want and it will give you a list
of functions that might do what you need.
Generalizing the types a bit usually helps. Searching for either  m a -> n m
a   or   IO a -> m a   would give you 'lift' and 'liftIO' as one of the top
results.
