I used thinset on mine, but people have had varying degrees of succes using Bondera and other similar products.
More importantly - You should use a cement backer board to attach the tiles to. You should do wood -> thinset -> cement backer board -> whatever adhesive you choose -> tile
Wood warps and that can cause cracks in your adhesive, grout and even tile. Cement backer board is cheap, easy to cut and really doesn't add that much weight.
