Vomiting can be a sign of many medical conditions, so if this is a regular thing, and if you haven’t already done so, do get this checked out by your vet and ask what they recommend.
Many cats can't digest dairy, and while live yoghurts may be good for human gut health, the microbiome in cats will be very different to ours, being obligate carnivores rather than omnivores like us. I also know for certain neither of mine would touch it.
But our two are frequent vomiters. The vet found nothing wrong, with one it’s just hairballs, so she’s on hairball control dried food, which helps but doesn’t totally fix the problem. The other just has a sensitive digestive system. We find all cat treats set him off (so no more Dreamies, poor lad), and if we complicate his diet too much by switching up with different foods. If he’s going through a pukey phase we put him on a good quality dried food for “sensitive tums”, which is smaller kibble and avoids triggering grains etc, and try to keep him away from the Hairball control food. We also realised he binge eats dried food at night and throws it up nearly every night, so we hide the dried food at night and just leave a little good quality wet cat food down (Applaws tuna is good - not too many grain fillers etc) which mostly fixes it. But every cat is different, so vet check first.
