我应该怎么闻？ This can also mean "How should I be smelling?" 闻 is an active verb. I believe you are trying to say, "How should I smell?" It is better to say, 我身上味应该怎样? which translates literally as "How should the smell on my body be?"

Wife said to her husband:
- Where have you been all night?
- Visitting my friend.

- Play mahjong.
- Play mahjong? But why do you smell of whiskey?
- You think I should smell of mahjong?
妻子对她的丈夫说： You don't need to use pronouns in familial relationships. It is defined in terms of the speaker. If you follow English "her husband", in Chinese you implies that she does this to every husband not including hers.
- 整夜你去了哪里了整夜？
- 我的朋友的家。 This is a routine conversation and you got it quite right. Anything more formal, i.e. in proper grammar etc, would have become unrealistic to real life situations.
- 你那里做过什么？Your use of 过 is most appropriate since it is an accusational tone the wife is using. Using 了 is too mild. Good job!
- 打麻将。
- 打麻将吗？但[Too formal]为什么你闻起来像一身都是酒味？ Or more accurately, 一身都是威士忌味?
- 你想，[Too namby-pamby] 喔? 我应该是怎么闻？[像]麻将味吗？
I am correcting from the tone of your Chinese version. The English version is more sneering than accusatory. Anyway, you captured the more common happening in a Chinese situation. Good joke!
