If you are looking for writ recipes, check the brewer and chef in any major city, they now sell writ recipes. If not, just go to the first zone in Caldwell silver and search backpacks, you should find recipes pretty easy that will be leveled to that area(vr1).
People are less likely to sell recipes for VR1, 5, and 10 as you need to be in very specific zones to find those recipes; once you get into VR range you can jump to anywhere skipping those areas entirely or just be there briefly. Most aren't going to stay in those zones for long enough periods to farm for recipes regularly, you may have to go scour for them yourself.
I am missing some vr1-5 recipes but no where near as many as the pre vet level recipes (in particular level 25), they can be found throughout the whole of cadwells silver which gives people more time to find duplicates to sell. I'd put a shortage on guild traders down to not that many people on silver any more combined with more people deciding to try and 100% recipes known. Check some of the less popular traders and/or try to find a decent stealing run to try and get them yourself
