Beacon before startup... left on until shutdown.
Nav lights + Strobes are not 'required' during the day, but either Nav lights or Anti-Col's are required at night (refer CAR 91.233 and 91.511)... At night Nav Lights are turned on after startup and before taxiing... and the taxi/landing light would be flashed twice (and left on) to let people know you are moving (and to make taxiing in the dark easier

)...
Strobes go on when lining up on the runway... as mentioned, they're not required during the day, but as I am paranoid, I will use strobes during the day if the aircraft has them... anything that makes me more visible = Good... turn them off after landing and having vacated the active runway...
Landing Light is turned on when lining up... turned off after landing and having vacated the active runway...
The airlines have the 'on under 10,000ft' rule... most of the GA guys around Ardmore switch this off when vacating the MBZ... however, as my PPL flight examiner said to me during my test flight "You can leave that on if you like, I have not racked up 17,000+ hours to be killed in the Ardmore Training Area for want of a landing light, if it's good enough for the airlines to have it on under 10,000', it's good enough for us!"... he is a 737 captain with AirNZ
Given the poor eyesight/lookout that seems prevalent at Ardmore, I am inclined to agree with him!
