There are many, many, many different types and designs of vapes. There are plentiful ASICS on the market specifically for vapes and e-cigarettes.
The cheapest variety is a tiny PCB built into the microphone. It's three wires for the battery and heater, and that's it. Sometimes they include a cheap and nasty battery charger. All in a single grain of sand for almost free.
