My advice from personal experience would be to lose the vape. Obviously the approach that works for one person may not work for another, but I'll share my experience in hopes that it might help someone. I've tried quitting cold turkey in the past, but with no replacement distraction. I've tried with patches and gum, and vaping. I'll just focus on vaping.
No doubt that vaping seems inherently safer and healthier, but vaping is a lot of work. You have to find the right flavor (granted anything has to be better than cigarette smoke, right? So why are we all so finicky about it?), the right vape, the right settings, the right coil, and you have to have enough batteries on hand to get you through the day. Basically, you're still feeding the nicotine addiction with vaping, and when things would go wrong with my vape, I would eventually end up buying a pack of cigarettes. Especially in times of high stress. So - here's what has *actually* worked for me so far without little to no pain.
(1) I quit cold turkey 2 days before Christmas. I flew to FL to spend the holiday with my family. I did not have access to transportation during the trip, and no convenience stores within walking distance. Plus, it would have been totally awkward to sneak out in search of a cigarette. I am a TOTAL closet smoker when it comes to my family. If possible, quit during a time when you will be around people you don't feel comfortable smoking around for a few days. Try to go somewhere that won't have your usual triggers or situations and preferably somewhere you won't be able to sneak off and buy any nicotine products as easily.
(2) A week later, when I got back home and was around my typical triggers, I bought and assembled puzzles almost every waking moment while at home. This gave me something to do with my hands, and something to focus on very intently. This COMPLETELY distracted me from any cravings. It's also something you can leave and come back to any time you have a craving.
(3) I don't give myself permission, or make myself think it's ok to vape. It really does just feed the addiction, and from personal experience I know that when vaping fails me too frequently in times of high stress (rapidly burned out coils being one of the most prominent and annoying for me) I would go right back to smoking.
(4) I avoid even talking about the act of smoking.
Stay super busy and distracted, and don't feed the addiction with anything - chemically, physically, or psychologically - not vaping, not gum, not patches, nothing. This is what I've had the most success with so far. Puzzles are the key for me as silly as that seems.
