You bait people by making them think it is safe to do something when you know better that it isn't. This can be done with attacks, positioning, movement, etc., but really you use a combination of all of those things to achieve a good bait. Simply naming attacks that are common baits wouldn't be good for you, I feel, without diving into the reasons why they end up being good baits.
I'm going to assume you want Fox related answers, though if you main Falco like in your profile pic he works similarly. A classic example is a dash dance bait - you make them commit to an approach, dodge it, and punish them for missing. This would obviously be an example of a movement-based bait (with positioning as a factor). Another example is a Shield Grab bait - you hit their shield with a seemingly grabbable attack, like an aerial or a jab, but you're spaced well enough that the grab misses. OR, if you cross them up (land behind them so they can't grab.) That would be a pretty even mix of all three bait types in this write-up.
Fox can't auto-cancel the way Falco can, but a spaced Bair can provoke your opponent to commit to an OoS option that you're ready to punish, such as if they spotdodge, wavedash, or attack OoS. If you know what they're likely to do, you can try to make them do it.
I would suggest watching some sets with Foxes and see their decision making. Every time they get an opening, go back and analyze how they got it. See if they made their opponent make a bad approach, how they did it, and see if you can apply it into your own play.
