I feel like there was a name for this sleight of hand approach and I've been unsuccessfully trying to google it for a while.

I think Heisenberg introduced it and it's basically "putting hats on all variables in classical equations", like the Hamiltonian, for example. This should imply the classical variables were suddenly quantum operators, without stating the form of the operators explicitly.

By what name is this known?

Canonical quantisation was introduced by Dirac in 1926

Canonical quantization mentioned by @CharlesFrancis is probably the most precise answer. Colloquially one would often use term correspondence principle, also known as Bohr's correspondence principle, and the Ehrenfest theorem. However in reality these have more to do with the system's behavior than with the actual quantization procedure.

Note in this context that some phenomena, such as spin, have no classical analogs.

    $\begingroup$ This answer is much better than the previous one! What kind of answer is writing down one short line of words (a sentence)? And it is probably not what the OP is looking for. But, then again, who am I to judge? $\endgroup$
