It seems the package is using dpatch. If so, do the following:
 - get the source
 - copy it (pkg-vers and pkg-vers.orig)
 - cd into pkg-vers
 - dpatch-edit-patch <patchname>
 - do your thing
 - exit dpatch
 - cd .. ; diff -u pkg-vers{.orig,}/debian/patches/<patchname>.dpatch

Another option is to apply the patch in both directories, do your change in
one of them, and then diff.
