fire, roast
焙 centers on applying dry heat to food: roasting or firing, typically to develop flavor or make something edible.
焙 combines 火 (fire) with 咅, which likely contributes the sound and may relate to heating or drying. The exact historical role of 咅 is uncertain.
The left side is fire 火, and the right side 咅 looks like a mouth 口 over a stand 立. Picture roasting something over a fire on a stand, with the mouth ready to taste.
For ホウ, imagine roasting food over a fire and calling out 'Ho!' when it's done: Ho -> ホウ, the sound of satisfaction as you fire-roast your meal.
