I do agree that some (well, most) of the cyberpunk themes are still very much alive though.
Perhaps Steampunk is closer to this, given that "steam" was part of the first industrial revolution.
However there are some interesting ideas floating around that you could use to tell a pure-Fantasy cyberpunk story; I'm sure someone's tried a novel, but I am only familiar with the tabletop RPG http://cryptorpg.com/, where magic enables cryptography and messaging. From there you can recapitulate pretty much all of the dystopian power/narrative structures that make Cyberpunk what it is.
Magic-as-technology is a surprisingly under-explored concept, with the right magic system I think you could easily tell a Cyberpunk story.
This is a very common way to address magic when tradition sci-fi writers try to incorporate fantasy elements into their novels. It’s used in the Shadowrun universe, and in the novel The Rise and Fall of D.O.D.O as two popular examples.
