A couple of things Logan
If your juice has been sitting in bottle for a couple of months waiting for you to return to vaping, it could be quite nasty tasting now. I have a few bottles I let sit and came back to them after a couple of months and they were not right at all. Some juices don't age well. Get new juice at the very least. And clean the crap out of all your equipment! Old juice has a way of clinging to your stuff and new juice won't taste right.
When I first started vaping I need very strong flavors because after smoking my buds were near dead, as I got farther away from smoking I tended toward much lighter flavors and enjoyed the nuances. I really can't stand the strong flavors anymore, but if I started smoking again I would probably need them to wake up the buds again. Go to a vape shop and sample again to find something that satisfies taste (as well as stronger nic as others have said). Flavor preferences change all the time, go find flavors that satisfy you now, don't expect that the flavors that used to satisfy will still be your preference. Much of the time I vape now for the flavor, not just the nic.
Maybe you've lost the hobby aspect that was so appealing when you started. Explore different aspects of vaping to recapture the hobby drive. Maybe DIY juice or something, or new mods and attys as others recommended. Try some new tanks or builds. Find the fun again. Just getting away from smoking is not enough for most I think, it needs to be enjoyable... something smoking is generally not.
Whatever you decide to do... good luck with it.
