Does burning wood violate the law of conservation of energy?

Nope. Wood is formed by trees. Trees get their energy from the sun. When you burn wood you are simply releasing stored solar energy, in the form of chemical bonds, to release heat. Energy conservation still applies.

No it confirms it.

If the Law of Conservation of energy is found to be violated, then the new form of "lost" energy is taken into account and the law is restored. So...really can't violate it at all....

No. You can't violate the law of conservation of energy.
Burning converts chemical energy to an *equal amount* of heat and light energy.
E.g. say a piece of wood contains an amount of chemical energy = E1.
The ash and other chemicals resulting from the burning contain an amount of chemical energy = E2.
The amount of chemical energy lost = E1 - E2
The amount of heat and light energy produced will exactly equal E1 - E2.

The wood contains chemical potential energy. burning it converts it into heat, light, CO2, CO and various other chemicals. All you did was convert chemical energy into heat and light.

No, and nothing does.

Yes, it's magic.

You are not violating any laws of physics because burning wood is a chemical reaction. Wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapour, and ash.
I'm not a chemist but the reaction would be something like:
CH2O + O2 -->h2O+CO2+CO+C+N2
