Not that I know of.

The best is to read e.g. guest_arm_toIR.c and guest_arm64_toIR.c
and inspire from that. I think that usually, it is sufficient to
modify these files but sometimes, new IR instructions are needed,
or specific helpers have to be developed.

If you provide a patch, adding or modifying a test to cover
the new instruction helps to have your patch merged.
