Hm, I can't think of any specific recommendations, but I do have some suggestions for how to make your choice.
As has been said already, furigana (the hiragana guides written next to kanji) is going to be a big help, and it's pretty common unless the manga is specifically aimed at older audiences. Furigana helps with looking words up in a dictionary, if comprehension practice is your aim, although reading with a dictionary is going to be very slow (still worth it if that's what you want).
4koma-manga are usually decent choices, because they don't rely on too much continual context; failing to understand a couple pages isn't going to make it impossible to follow what's going on, because most of the strips stand largely on their own and establish their own subject/context. Although some comedy 4koma might have puns and references in them that could be difficult to grasp through casual reading.
Lastly, I think it's a great idea to choose something you've already read before in a language you do understand, so that you go in already understanding some of the basic character dynamics, plot direction, and other things that you can fall back on. You usually don't remember every line from every chapter of manga you've read as long as it wasn't very recently, so it'll still be relying on your reading comprehension, just with some added help from the familiarity you feel.
Dunno if any of that helps, but I hope you find something that works for you!
