Oh, crud. I was explicitly thinking about avoiding charmspam when I wrote that last line about being immune for an hour, and then I botched it. That's what I get for writing this stuff after I get back from work. I'll fix that, and add some defenses.
For Children of the Night, I will probably add the command limitations you mention, but I won't add a list of creatures. I want the effect to scale with level, so doing so would require me to provide a list of thematically appropriate animals at every level. If somebody else wants to do it, then okay, but that's more effort than I want to put forth.
For Mist Form, yeah, I'll add some stuff to Gaseous Form about natural winds, and explicitly call out that vampire vulnerabilities still apply to a vampire in mist form.

Yeah, it doesn't. That's what Vampiric Vigor is for. And none of this "Vampires can't take damage until they reach their coffin nonsense". I've never actually seen that come up in media, it's just that the creators wanted a way to have players fight the vampire and still force them to do the dramatic stake-them-in-the-coffin scene, which is typically done in media when the heroes sneak up on the villain, not after a climactic battle in which the heroes were undeniably the victors. We'll be having none of that, but vampires with supernatural regeneration are fine. Since they're explicitly vulnerable to nonlethal damage, this is acceptable.
The downside to these feats is that you need a racial hit die to begin with (one which you, at least, have claimed didn't seem worthwhile) and you also need to spend a feat on each one. Getting all of them takes 4 feats, which is more than half of a character's feats over 20 levels (discounting bonus feats). Flaws do break them a little, but that's because flaws are kind of absurd. Maybe I could put a limit on use more substantial than at-will, but even so. And I should probably add to Form of Mist that your gaseous form is personal only - sorry about that, it was an oversight. If you have a better suggestion than the Escape Artist ranks, feel free; they were a kludge to get it available at level 10 only, and not a very good one.
Thing is, though, they're not getting these abilities from their class, they're getting them from feats, which seem an ideal way to add modular abilities onto a character. I'm not writing a 4 level racial class, under any circumstances, because that undermines the entire point of writing a vampire template that's as compatible with multiple builds as a human. A prestige class of some sort for vampires who want their race to be a defining part of the character, maybe, but as a core part of the template, it's just counterproductive. And, honestly, I'm getting tired of writing more vampire material. So the prestige class isn't very likely unless somebody sells me on a really good theme.
