Assuming you mean "masked vigilantes" like say, DC's Batman...?
There's no "secret" really. You have to do what everyone else does--start by writing the character as a human being. Get to know your character. See if there are any themes or obsessions that rub off on the character. These themes or obsessions could be anything: from scissors and haircuts (Edward Scissorhands) to leafy green veggies (Salad Fingers) to sticks & batons (Daredevil) to bats (Batman) and beyond. Sure, some of the ideas will be crap, but some won't, which is why you look into and research _everything_.
Once you're doing that, work at it from the other end. Ask: In general, what kind of vigilante is this person? Pulp Fiction and Film Noir generally support five kinds:
--The detective, who solves mysteries and cold cases _for_ the police,
--The hitman, who hunts people down and takes vegeance (usually killing them with a specific weapon),
--The adventurer, who pursues his or her specialty to the ends of the earth (think: Indiana Jones, Tomb Raider, Flash Gordon),
--The "femme fatale", or the one who works in their civilian identity and tends to mix business with pleasure (James Bond/007 being the prime example of a _male_ femme-fatale type), or
--The psychopath....the "bad guy" who ends up doing good things. This need not be a "Joker type", as a superficially well-adjusted "Tony Soprano type" can work as well.
Looking into it from that end will inform you in terms of what the character _does_ when they hit the streets, looking for justice. You want to know what the character does because it will determine what sorts of equipment they'll carry.
But basically, there's no real "secret" or trick to it. The characters you see didn't _start out_ as refined and polished as they are now: they became that way thanks to a LOT of professionals working on them for decades, literally. Writing about a masked vigilante is no different from writing about a horror-movie character, or a love story, or anything else...
It still takes work and at least one or two original, clever ideas (and I'll grant you that the good ones that remain are hard to find). You have some work cut out for you--because honestly, in some cases an actual super-power can become a literary shortcut that expresses the character's nature.
But yeah, the best way to do it is to DO IT. Write the character as a human being and see what fits the character's life.
