Although the creature is attacking, it was never declared as an attacking creature. This means that abilities that trigger whenever a creature attacks won't trigger when the creature enters the battlefield attacking.
Zara, Renegade Recruiter
If a creature is attacking a planeswalker, that planeswalker's controller is the defending player.
The creature is returned to its owner's hand only if it's still on the battlefield as the delayed triggered ability resolves. If it's somewhere else at that time, it stays where it is.
