Any plans available for building a wood and fabric glider these days?

Indirectly, yes.
When you buy any one of a number of kit projects currently for sale,
you also get the plans. Happens to be a cost-effective way of getting
the peripheral stuff as well. Wood cost more than it did when gliders
were being designed for wood construction.

For example:
BJ-1b Duster Project
Kit is plan number is 371. Construction is well along.
Needs to have one aileron finished, Needs a canopy, sanding of the
wing LE.
It is bare wood, will still need some kind of finish.
