Where 'wake' means 'stop sleeping', in BrEng always use woke (simple past) and woken (past participle), I have just woken up, I woke my friend at 8am. AmEng is more tolerant of waked.
There are several forms of wake, some regular and some not. Present/past / past participle as follows:
wake/woke/woken
awake/awoke/awoken
waken/wakened/wakened
awaken/awakened/awakened
People sometimes mix and match these in confusing ways, using the past of one and the present of another.
