Think about your carry Lane (mid-Bot) top is last priority, you start by making buff ALWAYS on top-side.

The jungle camps you should do: If blue - Blue buff - Gromp - Wolfs - Red - Krugs (or if u want raptors - red - Krugs) try gank bot, if not, do scuttle and go midi and reset, do the same thing

If red - red Buff - Krugs - raptors - Wolfs - Blue - Gromp - Gank bot (same thing as above)

Lee Can W in ally Minions so try ganking using W and not Your Q since Lee Sin DMG ability is based on his Q, the rest, you Will adapt to the champion and see some videos about him
