Due to its porous nature and movement with temperature and humidity, wood is not ideal as a mould material or surface.  At the very least the surface would need to be sealed.  A coat of epoxy sanded smooth and polished back to a gloss finish would work to seal the surface.

You should then be fine to apply release agents and lay up without issues of the part sticking to the mould.  Obviously if you wanted an elevated temperature cure, then you would need to realistically make a proper mould using high temperature compatible materials.
