Basically, the carbon in the wood reacts to the oxygen in the atmosphere to produce CO2. As this is an exothermic reaction, it gives off heat.
Smoke is caused by either non-carbon elements within the wood reacting with the oxygen to form more noxious compounds, or the incomplete reactio of the caarbon with oxygen, causing partially reacted carbon to be released in the form of soot.

The elements that made up the wood recombined in different ways with elements in the air to form water, carbon dioxide, ash, and other products as well.
