Steve, if you can come up with piece of veneer (peel it of off some scrap) your possibly in luck.
Depending on the damage, clean/square up the damaged area(a good sharp chisel is handy here...used judiciously)
Now take your piece of scrap veneer and trim it to match the damaged area, possibly beveling the edges(slightly) on the bottom side to give you a "sharp" edge to match up to the surrounding areas.
I wouldn't use epoxy but rather something like titebond2/3 and glue up the piece in question, using some wax paper and a block to cover the whole area and clamp tightly.
After 24 hrs or whatever time you feel apropriate, remove clamp and peel away wax paper, if your fit up was correct and the veneer matches at all, a little sanding and you should not even be able to tell where the repair was made
I hope this was understandable, because I have used this technique several time with much success
good luck
