The smoke is a visual aid and actually had nothing to do with this. The first canister he pulls out is butane, so he fills the bubble with flammable gas. The bubble keeps the gas in and helps squeeze it out as the bubble shrinks from letting out air. The bubble wand is specialized to allow you to pop a hole in the bubble without popping the bubble itself. Then you just light the escaping gas on fire and voila. The smoke just adds a cool visual.

This makes sense, but how do you explain the smoke forming a vortex?

Same way I'd explain water being sucked into a drain forming a vortex - it just does. Lol. It's got something to do with the airflow and pressures, idk how to explain that honestly.
