Mix the sugar and warm water together and pour over the yeast. Gently mix together and sit for 10 minutes to activate.
Mix the flour and salt in a large bowl and add into the yeast and water mixture. Mix with dough hook until a smooth dough forms. If it is too dry, add warm water one teaspoon at a time as needed.
Turn the stand mixer up to medium and knead in mixer for 10 minutes until smooth and elastic.
Grease the inside of a large non-metal bowl with the oil and place the ball of dough in the bowl and cover with plastic wrap or a damp dish towel and set it to rise in a warm place for one hour until dough has doubled in size. I like to put it in the oven with just the oven light on which seems to be about the right temperature.
When dough ha doubled in size, punch down the dough and recover and let sit for another 10 minutes.
In the mean-time, preheat oven to 220 °C (425°F); fill large pot of water and bring to a boil; and cover a baking sheet with baking paper and set to the side.
Remove the dough from bowl and divide into eight equal pieces(each piece should be approximately 100 grams give or take five grams to make them even).
Roll each piece into a tight ball using your hand in a "c shape" and gently rolling on un-floured but clean work surface until a tight ball is formed.
Press your finger into the centre of each ball to form the hole and stretch the dough balls so that the hole is about 1 inch in diameter; let rest with cling film/ warm towel over bagels for 15 more minutes.
Mix your seed and bagel seasoning mix together in small bowl.
Once water is boiling, reduce heat to medium high and drop in bagels two to four at a time so they have enough room to float around.
Once they rise to the top, start your timer for two minutes and then turn each upside down with a slotted spoon or spatula and continue to cook for two more minutes.
Remove from water and using a pastry brush, brush each bagel with non-dairy milk and sprinkle seed mix over each bagel.
Bake for 20 minutes, rotating the pan half way through and transfer to wire rack to cool for 10 minutes before serving.
