How do you apply the solder paste manually to the IC pins or pads ? I've
tried and the paste does not stick anywhere (before soldering). I even tried
with a syringe and ended up clogging the needle.

IMO this is the most critical part in SMD. It doesn't matter if your
placement is poor, since the solder will try to align the components with
the pads (when soldering). But you need to apply an even coat (and right
quantity) of paste to each pad. This is were I fail.
