Ceramic tiles on masonite

I am a paintings conservator treating a painting on tiles by
Dominican artist Paul Giudicelli from 1964, and need suggestions for
readhering them to their support:

The support is composed of caolin-based British commercial tiles 6 x
6 inches each, forming a composite surface of 24 x 18 inches. The
tiles were glued to a masonite support reenforced on the back with
wooden strips. The textured side of the masonite faces the front.
Over time, some of the tiles have fallen off due to loss of
adhesion, while others are lose, or were improperly aligned during a
previous repair.  In addition, the masonite support shows signs of
infestation by wood-eating insects. For performing the treatment of
the support and properly securing and repairing the broken and
misrepaired tiles, we removed the tiles from the support with
ethanol-based solvents, repaired them, and now need to readhere them
to the masonite support. We are not sure of the type of adhesive to
use in order to obtain a strong bond to the support, and thus, would
appreciate any suggestions.
