I'd search for a teacher in your new location.
Or stay in contact with your old teacher.
With the internet, you can send recordings or video. With email, or posting them for anyone to see. You can get somewhat "live" advice that way.
Get recordings of the pieces you're playing. And books. Esp with the WTC, I know some of those are dance styles and aren't meant to be played exactly was written.
You can post on here for advice about the ways you practice.
I really think a lot is how the student practices, not as much about the teacher. The teacher can give you advice about the things you wouldn't know about otherwise -- a certain playing technique, the "real" way the music is supposed to be interpretted, etc., but the student is one who actually does the work and knows how they are practicing.
At the very least, play something. You can at least maintain your current level of playing.
Listen critically to your playing. Pick our your own mistakes and problems and then figure out your own solutions. Basically, be your own teacher. The tough part is knowing those little details about composers or style that aren't apparent from the music by itself -- Then you have to research books and recordings to discover it.
