Your larger company built up those things over time, but likely with management support and pushing and enough of it built into the culture that everyone realized the value. In your smaller company these things need to be done, and you need to be a champion of them. Pick your battles, but don't assume you can win every one at the same time. Pick the one most important to you or would have the most impact, champion it, and lead. You've seen nirvana, now you might just have to lead people to the promised land. Just don't be one of those people who are like, "When I worked at ($current_company - 1) everything was much better than here. No one here gets it." Be the solution.
