How to get nations to join HRE?

If you passed the third reform "Absolute Reichsstabilität", you get a CB with which you can force countries to join. But it generates AE.
Or you can force the capital of a country to move to an HRE province by various means and that would make them a member.
Some countries(Burgundy, Papal States) have events/incidents to join.
But otherwise it is very rare for countries to join. They can join voluntarily if they are small enough and the emperor likes them enough, but the AI only does it in rare situations(mostly when threatened by outside countries). In version 1.30.1, there was a bug which caused the AI to always join when they could, but this was fixed soon after.

Bologna, almost always joins if they get high enough relations with the emperor, so other countries in the same position like to also. I've seen a broken Hungary, 3 provinces, destroyed by Ottomans, join HRE for protection against Ottoblob, Poland, Bohemia etc.

Are your vassals supposed to join like Hungary?

Hungary should be in a personal union with you, not a vassal. And no, personal unions and vassals won't join the HRE. You could conquer and annex the vassal's entire country, add those provinces to the HRE, and then release them as a vassal if you wanted. Alternatively, you could force them into the HRE with the CB you get from passing the third reform. Or you can just wait the usual ten years, annex them, and add the land that way.

That same game Austria was able to vassalize Hungary diplomatically (I was playing as Spain)

The AI can do whatever it wants, lol. But the player should get the personal union with Hungary very early on. That and the union with Bohemia are two of the three most important first moves as Austria (the third is to conquer Venice).

Vassals and personal unions are added to the HRE. I am currently playing as Austria and my Byzantium vassal is in the HRE.

Was there some kind of event that fired or something? Or did you conquer a Byzantine core and add it to the Empire before releasing them? I've never seen a non-HRE subject get automatically added to the HRE.

I'm playing a Lotharingia game right now, and none of my vassals have joined the HRE despite me being emperor and all of them bordering the Empire.

Likewise in my games as Austria and Prussia- makes me think he restored Byzantium from a province that he had previously added to the HRE.
