The specific powers rarely map to D&D warlock powers, but then casters using a memorization/slot system was super rare before D&D popularized it too. As an overall theme, they have way more precedent than the Vance system.

If you look at the mechanical angle where warlocks are primarily blasty casters with a small bag of additional tricks available, again that describes a ton of games and shows. In fact, I'd argue that a refluffed tomelock covers more "wizard" archetype characters than the actual wizard class does. You may not find perfect fits for both the crunch and the fluff, but that's the case of any translation where one source isn't blatantly cribbing from another.
I think the OP was looking for more thematically and fluff examples. Not mechanical ones.
