Don't expect others to produce user stories or mock-ups, especially if this isn't already part of the culture. If you want to have user stories and mock-ups, start spending your time making those yourself and push them back to whoever is giving you the requirements for comment. If they question the need for you to be spending time doing that, it's an opportunity to ask for more specific direction on what you should be spending your time doing. Chances are it's a classic case of not knowing what they want, but knowing what they don't want, so by having their requirements reflected back to them they'll come back with "Ah, but what I meant was..." and you'll get more clear requirements. If it's still murky after that and you really can't get more concrete requirements than "We need this magic box made" then consider that some places genuinely just aren't good places to work, and consider this a learning opportunity and point for future comparison.
