Zerg Build Orders

Hi im curently in Top Platinium division  , i havent played starcraft for 7 months now , back then i was top diamond , and i dont rember any build orders or timings at all especialy for zvt and zvp , what unit compozitions should i use vs what  and all that stuff , all the builds i rember from back then are completley shut down now  , so could you please give ma few Macro oriented builds ( not cheese/ all in ) that i could use now ? 

Also if you could tell me when would be apropiate to scout , when the other races do get theyr techs ( so i know with what i have to deal and how can i deal with it ) would be really apreaciated. thanks
