What all should I include in my daily 1-2 hour practice regimen?

Hey, so I'm an intermediate singer been singing for a few years now but I've always been in the same place and I'm trying to get to the next level by practicing 1-2 hours a day. What are some good exercises to include in my daily regimen, because I'm doing a lesson a day, but I feel like I need to have a written down list of exercises to practice almost like a workout. 

Hi, Joshua! Here's an article on what to practice each day. Our warmups page also has warmups with different focuses for you. I encourage you to spend about 20 minutes max on your vocal warmup and then move on to ear training and song work!
