My own thought would be to conductive-epoxy the pad back down (or, if it's completely torn off and you lose it, conductive-epoxy down some copper tape), solder a bit to bridge to the existing copper, and then maybe the UV coating. That said, conductive epoxy is Not Cheap, and this doesn't look like the sort of connection that really needs the full treatment (I've only used it for lifted surface-mount pads, such as for capacitors).
