First thing I would suggest is not to watch the clock - having a routine for a baby is not about doing things at the same time every day because if that's what your aiming for you'll just drive yourself nuts.
With both of my babies I have always made a point of just doing things in the same sort of order every day so they know what's coming next. Some days it might be two hours earlier, other days might be three hours later but the order of things generally runs the same. So for my DS (who is four months old) this is how his day generally runs:

6.30ish - wakes up, breastfeed
Awake time
Morning nap (usually about 2hrs)
Awake time
Bath (usually happens early to mid afternoon)
AFternoon nap
Awake time, catnaps downstairs in the early evening
7.30ish - last feed and bedtime

He demand feeds during the day so I haven't included his feeds above.
Think about how your day normally goes, and the things you need to do and try to sketch something out.
It truly is trial and error and some days will go better than others but I have found both my kids have been much easier to handle and sleep much better when there is some predictability in their day.
Good luck
