The 関西弁（かんさいべん） equivalent of だ (or です) is や, and just like だ, や may be modified in several different ways. When followed by ん, やん expresses something similar to だよね, だろう, or でしょう. This means that it often translates as ‘right?’, or ‘isn’t it?’.
やん is primarily an expression that is added to the end of sentences, which means that it can be paired with any type of word.
