I had a break of ten years and had to re-start by doing a BFR (It's now called an AFR by the way!!). It's important to remember that this it is not a test and your instructor is permitted to give you instruction during it. Have you applied for an ASIC or AVID?(Aviation Security Card) this was one of the first questions I was asked as you will need one to go solo although you should be okay dual. Of course, you will also need a medical but again I think you can still do an AFR without it but you would not be able to fly without an instructor.
Swatting up on the VFG is a good start. Every training organization seem to handle the AFR a little differently and it will depend on whether you have a full or restricted license. Another change to the system is if you have a night rating or a Private instrument Rating. They now require separate AFRs each, at least my CFI say's so.
The rest is simply flying...basic maneuvers, forced landing, steep turns ,stalls etc. If you have a full license expect a short nav with a diversion and entry into controlled airspace; so try and bone up on some radio stuff.
You will be amazed how quickly it all comes back!!!. As it's been awhile I'd allow a couple of dual flights before you are done and legal again...Good luck
