My licence and rating expired 7 years ago. Last year, I had to do whatever flight training was required to pass a LPC, and pass the LPC. It's surprising how much you forget after 7 years, so it was basically the whole course in 16 hours for me. My FRTOL had expired by 7 years also, so this meant doing the Communications written exam again (required if it has expired by more than 5 years), but that was the only exam.
There was no difference in requirements between JAR and EASA. I did my LPC in August but waited until Sep 17 to get an EASA licence.
