I want to Masuda method an Azurill for a shiny one, and I have one set it perfectly (not shiny). It has the best nature, ability, and gender (Azumarill gotta stay manly). I know how to carry down a nature (Everstone), but how do I guarantee ability and gender?
How to copy a Pokemon in breeding

Gender is random and is based on the gender ratio for that species. For the Marill line, this is 50:50. There is no way to influence this.
As of Gen VI, a female pokemon has an 80% chance of passing down its ability when bred with a male pokemon (ie not a ditto). Male pokemon have an increased chance (60%) of passing down a hidden ability when bred with a ditto but there's no easy way to pass down regular abilities (I assume you want huge power) with a male pokemon.
You could fix this by breeding a female marill with the characteristics you want and using that, giving you a 40% chance of getting a male, huge power marill. This may also require Game of Thrones levels of incest.
