Mustang ignition cloth gloves, generate a spark(fire generation), similar to a lighter. The transmutation circles on the back of the gloves, allows him to manipulate oxygen and  hydrogen, controlling the density and pathways(fire manipulation variation). This allows him to increase the spark, created by his snapping, to increase the spark effects. This allows him to set things(creatures, objects) on fire (if flammable). One of the reasons "why" he was consider useless, was because water would cause him to be ineffective, (proven untrue in the manga, he can separate hydrogen from the water which is equally flammable as oxygen.)

Someone with this power, like Effigy, can turn things (objects, creatures) into flame, meaning the basic structure remains, but as a coherent field of fire. In theory, that would mean, he can turn a pond of water, into a pond of fire. With people, they become fire-based elementals. Chairs become fire shaped chairs. The coherent field of flame (object, creatures) can burn anything it touches. So, in short, he can make creatues into human torches and objects into flaming objects. At least thats how I see it.
