Jolenealaska's answer is spot on, but just to add, there is a case where this phrase could be used without directly answering a question about what you do. You could think of it as answering an implicit question, but also 'what I do' can be used figuratively, e.g. if you are really good (or confident) at spying, but not a spy.
If the subject of spying has been raised in a way that may involve you, you could mention your spying skills - whether or not your job is to be a spy - with this response.
E.g., your spying skills are being doubted, and you defend them:
A: Are you sure you'll be OK with spying on C? It's not easy, you know!
B: Relax! Spying is what I do!
E.g., a spy is being sought, but nobody knows that you are a spy, so you volunteer:
A: We need to find out what C is up to... We need someone good at spying. Who could do that?
B: I'll do it. Spying is what I do!
A: I always wondered what your job was...
P.S.: Psst! If you are a spy, you should probably keep it quiet ;)
Yes, that line is correct. "Spying" becomes a kind of noun, a gerund. "Plumbing is what I do." To use "spying" or "plumbing" in that way implies that you take the job seriously, that it's really a part of you. Here's a great explanation of gerunds from Cliff Notes
Yes, it is correct, and generally it is the more usual word order than "What I do is spying." A more precise term is "espionage", which like so many of our "more precise" terms, is simply the French word for spying. :)
A few more ways of responding to "What do you do?"
Espionage.
I'm a spy/intelligence agent.
I'm involved in espionage/the intelligence field.
I work for the CIA. (Really answering the implied question "Who do you work for?")
