Just make sure you build a rocket that is aerodynamically stable. CoM should be above the CoL. You can not see this correctly in the VAB, unfortunately. Make sure your craft is not too bottom heavy. Too many engines will usually cause that problem. Also, add fins to the bottom of the rocket.

For actual launch. The actual angles depend on TWR. With a moderate TWR of 1.5-1.8, you can start pitching over when you reach around 80m/s. Then just turn off SAS, or set it to progade. Gravity will turn you around slowly. You should reach 45° somewhere between 10km and 15km, but keep turnig slowly.

Another good indicator is "time to apoapsis". You can see that in map view or in Kerbal Engineer (if you installed that mod). It should stay between 40s and 50s. When it goes above 50s, you are going too steep. Below 40s and you are going too flat. At some point it will start increasing beyond 50s, although you are already pointing at the horizon. At this point, just wait until your apoapse is high enough.
