To be perfectly honest... DotA is a game about situations. Heroes are incredibly situational, items are almost all situational (as opposed to buy power), and the mechanics such as pulling and denying all contribute to influencing the situation. Basically you're free to mold the match and possibly force the other team to react to your actions. With this said, there's no 1 size fits all solution. If you gimme a list of heroes you'd like to lane with, I can bounce back multiple builds for you each for a different situation but because your opponents can also change their build up, things can get severely complicated.
Here is a few common ones to start with though.
A) Solo Dark Seer => soul ring rush. Double shell on creeps. Hide in Fog Of War inside exp range. Level up and repeat.
B) Trilane Stunner=> have 2 stunners/slowers mix for CC lock. Stack and pull all day long and keep enemies outside of exp range. If enemies try to get into exp range, 3 man stun gank GG. (Example : Sven supported by venomancer, leshrack, vengeful.)
C) Ranged Support => Basically the ranged support has to fight off both enemies while keeping you alive. Request mid / jungle to gank your lane at their convince. Requires good lane/mana/vision control for ganks to work. (ranged support example : silencer, dazzle)
D) Solo mid, get to level 5~6. Proceed to dominate other lanes with invisi/DD/haste rune. (example : pudge)
