Over the years I've been quite a lurker but I have upvoted several answers or questions that I eventually wanted to find back.
As I'm below 15 reputation, this answer does not really apply to me, because in my profile that part is grayed out.
So... is there a way for me to see that list?

Sadly, that isn't possible. Your 'votes' were stored as anonymous feedback, which by definition excludes having a list for them somewhere. The only way to see such a list is to obtain enough reputation (15) for actual vote privileges.
The other answer already answers your question. However, in the question you mention that your motivation is to be able to find the questions and answers again.
In the future, to do this, you could in addition bookmark the questions you are interested in. Bookmarking answers is not possible, but you could work around this by either bookmarking the question (and hopefully remembering the answer), or following the answer. Note that following a post would however mean you receive all notifications related to that post.
