Welcome to the running community. Your easy run pace should be more about feel, not so much time. Just as another poster said, read your body and go off of how you feel. Easy run pace varies from day to day, meaning my easy run pace mat be faster on some days than others. It should be a run to where you can conversate back and forth with a friend, but not too slow to where it feels like a jog.
Try looking up some running calculators online and type in your current race times to get an idea of what your easy pace should be. I would look at 3 or 4 different calculators and average out the easy paces they each give (they all use different training methods, but are almost always around the same time -- some may be 3-5 seconds faster or slower, so find the average between the ones you find).
As for your training, I would make sure I am bumping up my mileage (no more than 10-12% a week to ensure progression) and I would also do some strides or "quick sprints" after the easy runs -- they will improve leg turnover and give you a little bit of speed action. Just as you train your slow-twitch, work on your fast twitch. With that said, once you've been running [consistently] for at least a good month, you can incorporate some workouts such as tempo runs, fartleks, and even speed intervals (200m rpeats, 400m repeats, etc..) in order to better improve your race times. Make sure at least one day out of the week you get in a long run (most runners, inluding nyself choose Saturday as our long run day). This should be the longer run that you complete for the week. Also, make sure to take one down week every 4-6 weeks... doing some very easy mileage or easy workouts during this week will help your body recover and prevent you from getting injured. Work on your core (abs/lower back), lift some weights, and take care of your legs!
Best of luck on your new adventure.
