As written bu another poster, practice, practice and practice.

Hot air works really well with solder paste.

For soldering ic's with many leads, one technique that works really well (with practice) is to apply liberal amounts of solder flux (which by the way makes cleaning up more difficult) and tack two corners with a solder iron (with a minimal amount of solder on the solder iron). Using a "chisel" type solder tip, apply a small amount of solder to the chisel, then at a moderate speed, wipe the chisel tip (solder side) along the pcb/ic leads.

You will be amazed a the results.

You will need a good magnifier to inspect your work.
What method of soldering do you use. I have done some research on this and found many ways but none seem reasonable. I can make the boards but have not figured a way to solder them.
