BFRs
You got part of it. I would interview your client and read through his logbook to get a sense of the flying he does. At that point, you tailor his BFR to his needs.
You should hit some of the more basic points in the PTS, such as currency, medical certificates, etc. You could have him plan a simple cross-country and watch him get weather. After he plans the x-c, you can review his flight log and ask him a question or two about how he derived his calculations. You can then take the sectional and ask him about a few symbols. I would go into some depth about airspace and TFRs, etc.
At the start of the flight, you could ask him to start off on the x-c. When you're satisfied he knows what he's doing you can give him a diversion. On the way to that airport you can give him a stall or two, perhaps MCAS and constant-altitude turns, and pull the engine for the off-airport emergency. At that airport, work on landings with at least two stop-and-goes so he at least has currency to carry pax (your last at your home field would be the third full-stop). On the way back, give him some hoodwork. All this can be varied, depending on your client's needs.
Finally, a BFR is not like a practical test or stage check. You want to be sure he exhibits knowledge and flies safely, but you're not out to break his balls. One can usually tell shortly after the oral begins if someone knows his/her stuff and how good a pilot the person is a few minutes into the flight.
Hope that helps. Good luck with giving your first BFR.
