How do I halve an egg?

Whisk the egg, then measure by weight or volume and use half. One large egg is about 50 g (without shell), so use 25 g.

Should I halve leavening agents exactly?

For halving, scale leavening agents exactly. The non-linear scaling issue mainly applies when multiplying recipes above 2x.

Does oven temperature change?

No, keep the same temperature. Reduce baking time since the smaller quantity will cook faster. Start checking 5-10 minutes early.
