What you're looking for is Mezzanine:

http://beta.kainx.org/articles/6

The basic procedure is something like this:

1.  mzimport -L foo.src.rpm
2.  cd foo
3.  mzprep
4.  <Make changes to source tree found under work/>
5.  mzpatch -n foo-change_description.patch
6.  <Add patch to spec file>
7.  mzbuild
