It's undergone combustion to become gaseous particles.
Explanation:
Wood is (largely) made of carbon and hydrogen in the molecular form of cellulose.
Take the carbon in the wood for example;
the carbon burns with oxygen to form carbon dioxide - a gas. The gas diffuses away from the area of combustion, leaving no mass behind.
The same is true for the hydrogen in the wood;
the hydrogen burns with oxygen to form water that is heated by the energy present (in the form of heat) to form water vapour and thus leaves no mass behind.
