how to you make the passive voice in Japanese? 日本語で passive voiceを　どう　つくりますか？
also, what is the difference between asking
 作りますか  and 作るのですか？

Sentences become passive if you attach れる/られる into the stem words.  
e.g. おこす(wake people up/active)→おこされる(be woken up by somebody else/passive), しかる(scole someone/active)→しかられる(be scoled by somebody else/ passive).
