I do them with a broad tip and just any solder wire. SOIC is easy, but TQFP can be hard if the pads are too small.I do SMD soldering by hand all the time. Get the finest soldering iron tip (0.38mm) and finest solder wire (0.79mm).
I use 0805 parts and SOIC when available.
You will need either two soldering irons or a tweezer tip in order to remove SMD resistors and capacitors.
I often use a blob (or two!) of bluetak to hold the IC in position. Generally you put it across two corners, to the PCB so it doesn't touch the pins or pads (because it can make them greasy). That gives you time to get the IC positioned perfectly.I find the trick with TQFP packages to be very accurate positioning and get one corner pin soldered down, then do the opposite corner. ...

Then solder the rest. "Flood and drag" works for many people ...
