You can say something like "aren't you?" "don't/didn't you?" or, most commonly, just "right?" eg: "You're going home now, aren't you?" "You went to Spain last summer, isn't that right?" "You bought that coat at the mall, didn't you?" "You have a test tomorrow, don't you?" In all of these examples, you could use "right?". eg: "You're going home now, right?"

There are two ways. One is hard, but good for your grammar. The other is a lazy option, but very easy. 1' Use a tag question. 'You're coming home, aren't you?' . Tag questions have to echo the auxiliary verb and subject of the sentence. Native speakers do this instinctively, but learners have to think a bit harder to get the right auxiliary (have/has/had/do/does/did/is/are/was/were) or modal verb (e.g. can/could) in the positive or negative form and the right pronoun. 2. Just add 'Right?' 'You're coming home, right?' This is an American form which is becoming more common worldwide, especially among younger people. It's lazy but very simple.

In English, the word "no?" at the end of the sentence is translated as a tag question, which have many varieties. It's an annoying part of English for a Spaniard because each form of a tag question fulfils exactly the same function as "no?" See http://en.wikipedia.org/wiki/Tag_question
