I have a 5x12" sheet of Cherry Wood, 1/8" thick, that is not quite flat.
How can I straighten it, and keep it straight?

You could rim it with a really sturdy frame, if not slots in a box then a
thick metal frame. (Sorry, I don't know what a lens board is so I can't
tell if that makes sense in your application.)

A lens board is part of a view camera. It fits into a frame on the
front of the bellows to hold the lens. To change lenses, you change
the board.

The advantage of this arrangement is that you can tilt the lens to
correct for parallel distortion and such as well as moving the lens up
and down to get 'impossible' shots.


Do I need to find a straight piece to start with?

That's your best bet. It's a small enough board.

I'd definitely get a better piece of wood. Flatness of the lens board
is critical on one of those camera.
