i have a tool that may do what you want. i've used it for
peptide/lipid interaction, to define the lipids that are under the
peptide. as in a membrane simulation the normal to the bilayer is
typically the z-axis, you'll have to rotate your system to conform to
this convention. i think you can do that by using editconf to
generate one such structure, and then with trjconv you fit all frames
to that reference structure. contact me off-list if you want to get
the source of the program.
