Event independent code:

local azeriteItemLocation = C_AzeriteItem.FindActiveAzeriteItem()
if (not azeriteItemLocation) then return end

local azeritePowerLevel = C_AzeriteItem.GetPowerLevel(azeriteItemLocation)
local specID = GetSpecializationInfo(GetSpecialization())

for slot = INVSLOT_FIRST_EQUIPPED, INVSLOT_LAST_EQUIPPED - 1 do -- exclude tabard
	local item = Item:CreateFromEquipmentSlot(slot)
	if (not item:IsItemEmpty()) then
		local itemLocation = item:GetItemLocation()
		if (C_AzeriteEmpoweredItem.IsAzeriteEmpoweredItem(itemLocation)) then
			local tierInfo = C_AzeriteEmpoweredItem.GetAllTierInfo(itemLocation)
			for tier, info in next, tierInfo do
				if (info.unlockLevel <= azeritePowerLevel) then
					for _, powerID in next, info.azeritePowerIDs do
						local powerInfo = C_AzeriteEmpoweredItem.GetPowerInfo(itemLocation, powerID)
						if (powerInfo.selected and C_AzeriteEmpoweredItem.IsPowerAvailableForSpec(powerID, specID)) then
							print('Azerite power:', powerID, powerInfo.spellID)
						end
					end
