Max Maven - Verbal Control
Max Maven - Multiplicity
Jon Raucherbaumer - Hobsonian hanguide
Hector Chadwick - Art of equivoque (highly recommended tbqh - absolutely next level)
Mark Elson used to do a lecture - He does have some work in a live lecture, which is great. Apparently, he's working on a book...
The Berglas Effect has many chapters dedicated to it also if one can find it.
These are all complete sources of quiverkay - as I've found them to be, however, each author has their take on what's vital and the general hierarchy of rules to follow, generally, there are about 13 rules for good EKVK. After adequate study, you will probably end up with your own hierarchy of essential factors, though some are just non-negotiable, these you will discover through comparing and contrasting these publications/videos, you can comfortably break other rules as Berglas breaks some of the rules mentioned by Hector, but clearly, it worked for David, it's just about understanding the material.
I'd recommend reading as many of these as possible, Maxs' verbal control being the foundations and then Hobsonian-Handguide and Art of Equivoque to expand on the general rules and how much more sophisticated you can make it.
Multiplicity has an element of equivoque titled "The high-end gambit". It seems no one knows about this even though it cleans up almost every equivoque procedure that you may come across - highly recommended watching after going through the foundational stuff. Max also issues a redaction of a pressure technique that was misconstrued by people in verbal control to do with his approach to tone and offering enough ekihvahkey routines here to give you a general idea on how to do almost any. But just for the high-end gambit, this is worth its weight in gold.
Berglas expands on tone and body language, employing naturalness, but you can get the same ideas and principles through other work such as Dariel Fitzkee - Magic by Misdirection.
Jons' Handguide covers Marlos' pellet and how to navigate 2,3,4,5+ object quiverkay includes a few 52-1 routines also. A different approach in the way he defines The VeeKay from the usual as he makes it to be "game-like" through his rules, not all are fundamental rules as a few are taste.
Mark Elsdon covers quite a lot of great material in his live lecture, and of note is his tri'mpromptu routine (really looking forward to a better name for this in his book. I prefer my own name "Phone in the middle") - which is a free will style effect using 'vokay (Which is excellent, this is a nice direction to take equeevok)
After reading all the above (as much as you can get your hands on), I recommend reading the Jerx talking about Eckweeevohquay - though I don't agree with the definition of "First wave equivoque" (which is simply to do it incorrectly, if it fails at doing what it's supposed to - it is no longer what it claims to be, why categorize something as something it isn't. quite frankly bonkers.) I do enjoy the ideas he presents otherwise about tone, pacing and structure.
There are plenty of single effects using equivoque in many places. Still, before you learn individual effects I suggest taking the time to just study up on the principles so that you can comfortably perform the material without having blindspots in your technique, I don't think most single effects teach as comprehensively as a complete study of this and i think we all owe it to equivoque (and ourselves) to do it well.
Edit: also don't believe the nonsense about having to do it quickly, that's totally bogus, you can do this slowly and with gravitas if only you're careful with the words and tone you use.
It's a glass cannon; treat it well, and it's beautiful and powerful, though if you mistreat - it'll shatter, and the illusion is gone.
Okey'Dokey, that's my post on Okey'voqey - (magicians/'s(s'?) choice)
