Where are you located? There are a lot of pilots around looking to split time and get flying, that would be the best way in my opinion, especially if they happen to be a CFI. But assuming your medical and BFR are good, hop in with somebody who has been actively flying, one of you toss on a hood and both log PIC once your both comfortable with each other. Get a few good flights in, get your mojo back, some recent time in the logbook and go from there.
