Have a nice day.

Hello! This is a fun question!

I'm gonna narrow the scope a little, because if I did every Star Trek species we'd be here forever, but I'll try to hit all the main ones.

Andorians: I could see Andorians fitting neatly into the realm of Pantoran or Chiss characters pretty easily, and what little we know about the Chiss feels a lot like it could parallel Andorians in their earlier, more isolationist histories. I particularly feel like the rigid social structures of the Chiss and their military philosophies would fit quite nicely with Andorian values. Likewise, Pantorans share some similarities with Andorians, like exceptional hearing and coloration. Additionally, the tradition of garnering tattoos to indicate family and allegiance amongst Pantorans does feel similar to Andorian chitin patterns.

Humans: Humans across all universes are pretty much the same, let's be honest. If you take an average Star Trek Human civilian and plonk them down on an average Core World in the 'Wars universe, they'll do just fine.

Vulcans: Of all the species, I feel like Vulcans prove to be excellent candidates for Jedi recruitment, but that's not actually a species, so: Kel Dor. Hear me out: they have sages, they're largely mysterious, they are on the whole very force sensitive (psychically powerful) and they keep much of their culture and traditions to themselves. It's a stretch, admittedly, but I think it kind of works.

Trill: Phydolons feel like a good match. They're a symbiotic species which form a kind of gestalt consciousness between a mammalian host and a fungal symbiote, who value wisdom and spirituality.

Klingons: The Noghri might not feel like the most immediate option to come to mind, but bear with me. Noghri are skilled warriors who utilise technology and an array of natural weapons and defenses, place high value on honour, and function societies built upon familial clans. It's not as much of a stretch as you might think, looking at that. Just as the Klingons are honed for war, the Noghri are uniquely suited for combat - though the Noghri are most well known for being assassins, rather than front-line warriors.

Orions: The Falleen, hands down. Green skin, dark hair, known to use powerful pheromones to influence others, regularly associated with major crime syndicates... it's hard not to see the parallels. It's tempting to say Twi'leks here, but honestly I feel the Falleen are a much better match.

Ferengi: Muun in general, and the Banking Clan in particular. Muun are extremely intelligent and naturally gifted at mathematics, and while the Banking Clan gives them something of a negative reputation, most Muun are pretty decent folks. Sounds familiar? Wildly different physiologies aside, I think the Ferengi and the Muun have a surprising amount in common.

Tellarites: It would be incredibly lazy to say Gamorreans here, so I won't. Truthfully, with the minimal lore on Tellarites that we have to work with, finding an equivalent for them in the Star Wars universe is a bit tricky. I'd be inclined to say the Gran, perhaps, for their colonial tendencies and agricultural leanings, but even that feels very weak to me.

Mandalorians: Mandalorians are not a species but diverse individuals who follow a shared creed, and therefore I don't feel it sensible to include it with any of the above options which are based on species. Additionally, there are at least four kinds of Mandalorians, which further complicates the issue: Death Watch, the Children of the Watch, the True Mandalorians, and the New Mandalorians. Your choices narrow down to child-abducting-hyper-militant-terrorist group, weirdly-genetically-homogenous/militant-pacifist group, militant-but-mostly-reasonable-and-kinda-culty group, and a virtually non-existent faction of militant golden-age-Mandos-cut-down-before-their-time. With all of these, your mileage may vary wildly. I could see Vulcans being attracted to the New Mandalorian philosophies, I suppose, and Andorians would probably be all over the True Mandalorian option, but it's hard to say more beyond that outside of individual circumstance.
