Oh, sorry. You meant something for reading, right?
You might want to take a look at this list:

These are books recommended by くもん for Japanese students. 5A-2A is Kidgarden level, A is 1st year level, B is 2nd year level and so on. But don't get fooled by the level, even children books all written in hiragana have lots of vocabulary most Japanese as foreigner language don't cover. You could try first some at A level, and if you find it too hard, try easier books at 2A or so.
As an intermediate level textbook, I recommend you "文化中級日本語" ("Bunka Chuukyuu Nihongo"). It's a little bit expensive and all in Japanese, but recordings are great and it covers a lot of vocabulary/grammar patterns.
If you are like half-way to Intermediate level, there some 初中級 level books like "日本語中級J301 ―基礎から中級へ―", which are meant to cover gaps in-between the two levels, and advance from there to an intermediate level. It also covers a good amount of Intermediate stuff, and if I'm not mistaken, there's an edition with English translations.
