OK, then it's a naming issue. Because when players hear vampire it comes with a very specific set of aspects. I don't want to get into definition battles with players about what vampires can do in this plane or that
Vampires belong only in Innistrad, end of story, in my book!
The thing is that there are a number of common races in Magic where most planes have their own twist on them. This is to a large degree driven by the game having many cards based around creature types (e.g. "Elves you control get +1/+1 and have Reach", "Tap two untapped Wizards you control: return target creature to its owner's hand", "Sacrifice a Goblin you control: deal 1 damage to target creature or player", or "Castle Ziderburg comes into play tapped unless you control a Vampire."), and being able to use those from many different sets together makes deckbuilding interesting. But every plane should be different, so the different creature types have different twists in different places, and they often branch out into other colors than their core color to show their differences.
So, for example, on Ixalan the vampires are organized religious conquistadors from across the sea, seeking to recover a legendary artifact from the untamed wilds of Ixalan. These vampires are black and white, to various degrees.
On Innistrad, vampires are degenerate hedonistic nobles that love partying and fighting. These guys come in black and red.
And on Ravnica, you'll find the aforementioned psychic vampires draining their victims' souls and minds. These are black and blue.
Vampires are one of what the designers call "characteristic" creature types - usually fairly small and showing up in fairly large numbers across different rarities. In other colors, you have green elves, red goblins, and blue merfolk (they've had a hard time finding one for white). They show up as a race on a lot of planes, but not all - for example, the recent set Kaladesh instead had Aetherborn as the black "small dude" creature type, with just a few of these also taking on vampiric characteristic (in that case, treating "vampire" as more of a class than a race). For vampires, being a characteristic race is a relatively (about 10 years old) development - before that, they were instead treated as one of Black's two iconic creature types (big, powerful, usually only at high rarities) but since they often competed with Demons for that slot, and because the previous black characteristic race Zombie was fairly limited flavor-wise, they shifted vampires over.
