technically, it's ionized particles, heat energy and photons.

Flames are visible light energy - released as a result of a self-sustaining oxidation reaction involving some fuel, air and free radicals - heat triggers the reaction - heat released from the reaction provides additional heat to continue the reaction - the reaction continues until either the fuel is consumed, the air is gone, or the free radicals are gone (which can be done chemically with some types of flame retardants to extinguish a flame without smothering or lowering the temperature).
The flames are energy released in the form of visible light resulting from the chemical reaction - they are not the same as the smoke. The smoke is particles suspended in the air - byproducts of the reaction, remnants of the fuel and/or air after the chemical reaction is over. Smoke can also include water vapor where the thing burning is wood or other plant material with some water.

The flames from any combustion reaction consist of the visible light radiating outwards. A candle flame is an excellent example...hence the use of candles.

The flames and smoke are the same thing, only at different temperatures. It's mostly carbon atoms, and partially-burnt hydrocarbons. When they are hot, they glow. As they cool, they stop glowing and turn dark, becoming smoke.

It is hot gas heated by the chemical reaction of whatever is burning.
