Meditation: Twice a day, nearly every day, more or less directly after getting up and before going to sleep. Currently both sessions are 10-15 minutes each.
I mostly do void meditation, i.e. trying to let go off any thoughts and concentrate on a mantra, a candle flame and/or similar.
I've also done 30-minute meditations sometimes and if done right those are where the fun really starts. But I don't have the practice yet to meditate properly even every other time, so I rather work slowly towards that, instead of investing 30 minutes every morning of which I can expect to be daydreaming more than half the time anyway.
Prayer: Whenever I feel like it. Most often while lying in bed, but also throughout the day. Silently, sometimes also whispering/speaking.
Normally it's not the asking-for-something kind of prayer, that wouldn't really combine well with my theology anyway, for things like that I rather use rituals, sigil magick etc. (I'm agnostic to whether that actually works, but how can I know without trying?). If I ask for something mundane via prayer, then about strength and direction or simply luck. I rather ask for spiritual things, like getting better at perceiving my deity.
But mostly it's just about the reverence I feel.
The wording is almost always spontaneous, but I might include parts of poetry, song lyrics or prayers that fit. Parts are also without words of any kind.
The huge majority of my prayers are directed to the Dark One of whose essence we are, but I use several names to refer to certain aspects of it which others may consider separate entities.
I also sometimes say prayers to other spiritual beings, but I consider them on a completely different level, so I can't really compare that.
