Repair (fixing back) lifted power thru hole pad+trace
Epoxy should be a great choice. I would tape the back of the circuit board so that the epoxy can go in the hole and self-level, put the epoxy in, and then use tape to hold the trace down. 

After that, you'll need to re-drill the hole for the replacement component. The existing hole was probably plated through; if it was, you will need to solder the component onto both the top and bottom traces.
